Application filed October 8, 1914. Serial No. 865,639.

vices adapted to be used for disinfecting purposes.

My invention has .for its object primarily to provide a fumigatingdevice designed to be employed especially inthe dumb-waiter shafts of buildings and like places for dis-k infecting the atmosphere thereof'when contaminated by impurities from garbage and other refuse, and wherein is provided an absorbent feeder or wick leading from a supply reservoir containing a volatile liquid disinfecting material which is delivered to the feeder in suitable proportions, the vapor or fumes therefrom being` distributed to permeate the surrounding air through the me-l dium of one or more absorbent distributers on the feeder, thus preventing the spreading of offensive odors as well as maintaining proper sanitary7 conditions.

Other objects of theinvention are to provide a tubular container or pipe in which the absorbent feeder is mounted; to provide on the tubular container one or a numberA of perforated casings, or cups; and to provide a number of spaced orifices in the container through which the vapor orfumes of the disinfectant are also distributed.

7With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawing` forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claims at the end of the description.

In the drawing, Figure l is an elevation of one form of fumigating device embodying my invention showing the manner of its use in conjunction with a dumb-waiter shaft. Fig. 2 is an enlarged sectional View, partly broken away and partlyin detail, of the device. Fig. 3 is a view, partly in section and partly in detail, taken on the line IlI-HI of Fig. 2. Fig. t is a section taken on the line lV--IV of Fig. 2, and Fig. 5 is a section taken on the line'V-V of Fig. 2,.

The fumigating device has a tubular container, or pipe 10 composed of sections, as 1l, 12, 13, which may be of a suitable number whereby the length of the pipe may be shortened or lengthened in accordance withthe height of the `dumb-waiter shaft, as 14 or other place, and the opposed ends cf theI sections are formed so as to snugly intert with each other. The pipe 10 is disposed vertically in the shaft and may be held stationary therein by any suitable means, for instance by a number of spaced straps, as 15, secured to one of the usual guides 16 in the shaft. Each of the sections of the pipe 10 is of a length approximately euuivalent to the height of each story of the building in which the device is used so that the upper end of each section will terminate at an entrance, as 17, to the shaft, and through the pipe of Aeach section are a number of spaced orifices 18.

@n the top end of the upper section 11 of the pipe 10 is a receiving cup 19 of any suitable shape having an opening in its bot tom which communicates with the passage through the pipe,.and the lower end 0f the bottom section of the pipe leads into a drip cup 2O which is also securedA by a strap 21 to the guide 16. In proXiinitv to the upper ends of the sections 12 and 13 of the pipe are provided casings, or vcups and 23 which are similar in formation. While the cups may be of any desired shape, each cup is preferably formed with verticallv disposed side walls 24, 25. and end walls 26, 27 which curve downwardlv toward the pipe in a parabolic shape so that the end portions of each cup will extend in opposite lateral directions from the pipe. On the top of the end portions of each of the cups 22 and E23 are two covers Q8 and 29, each having a number of perforations 30 therethrough, and the opposed ends of the covers of each cup are hinged thereto so as to be swung upwardly toward the pipe. Through diametricallv opposite parts of each section 12 and 13 of the pipe areV openings 31 and 32 providing communications between the interior of the section andthe cup thereof.

For the purpose of providing a suitable source of supply of disinfecting material for delivery to the receiving cup 19 and to the pipe 10. a reservoir, or tank, as 33, is provided. rlhe supply tank 33 may be of the form of a well-known substantially square or rectangular metal can having at its inlet through one end thereof the usual projecting eXteriorly threaded boss, as 34,-, Which is ordinarily closed by a threaded cap, not shown. This type of tank is preferably employed, in order to permit the supply of the disinfecting material to be conveniently replenished at intervals by enabling a number of the tanks to be filled with the disinfectant, as 35, at one place and then delivered for use to the various devices. The disinfecting material be of any suitable formula in liquid form having vola-Y tile properties whereby'the vaporl or' fumes therefrom will permeate the Asurrounding atmosphere when distributed, and to allow the disinfectant to be properly delivered to the' receiving cups 19 and to' the pipe 10 the supply tank is detachably held to the" dumb-waiter guide 16 by meaiisof a strap 36 or otherwise which is arranged so that the tank will be in an inverted position for its outlet to: be disposed over the receiving cup of the pipe 10. On the threaded boss 3ft of the tank is removably applied valve, as 87, of any ordinary type adapted to be adjusted whereby the flow of the liquid disinfectant from the tank may be suitably regulated, 'and to establish a uniform How of the liquid lon the interior of the valve is soldered or otherwise` secured one end of a vent tube 38 which passes through the boss of the tank and extends upwardly thereinto toward its other end for air to be admitted into the tank through the valve during the passage of the liquid.

vServing to allow the liquid disinfectant to be delivered and distributed through all the sections of the pipe 10, in the pipe is disposed a feeder, or wick 39 made of woven thread or other absorbent material, and this wick is off a length tok extend from the receiving cup 19 through the pipe into the cup 20 so that the dripping from the wick will be received therein. In the cupsV 22 and Z3 vare distributers, as 40 and 41, each of which may be in the forni of an absorbent wick or a batch of cotton of sufficient quan` tity to lill Iboth ends of each cup', and parts of each of these distribiiters aredisposed through the openings 31 32 of the pipe which communicateuwith theinterior of the lcup4 thereof so as to Contact with the absorbent feedenor wick 39. Wlhen the olisinfect'ing liquid is delivered from the supplyI tank through' the valve 37to the' wick 39 the liquid will be absorbed thereby, and through capillary attraction part of the liquid will be conveyed to the distribiiters AJCOand 4i. Thevapor or fumes of the disinfectant will then pass through the per forated coversof the cups and through the orificeslS lof the 'sectionsof the pipe for pernieating q the y, surroiinding atmosphere whereby are spreading' af Qfrasive @dors wat be prevented 'as wen as h'iaitaiig. 'p'i'p'er sanitary' conditions.
